Patented Apr. 17, 1951 UNITED STATES PATENT OFFICE LAMP GUARD AND HANDLEFrancis 0. Kollath, Chicago, 111. Application July 23, 1945, Serial No.606,516

The present invention relates to a lamp guard and handle andparticularly to means for securing a lamp guard to a handle, the presentapplication being a continuation, in part, of my applicacation SerialNo. 505,319, filed October '7, 1943, Patent 2.394597, February 12, 1946.

An important object of the present invention is the provision of new andimproved means for detaching and attaching readily and quickly the lampguard from the handle by the mere manipulation of co-operating elementsso as to effect quick and easy replacement of a lamp bulb which isthreadedly received in the screw socket in the handle and within theguard or cage.

Numerous other objects and advantages will be apparent throughout theprogress of the following specification.

The accompanying drawing illustrates a selected embodiment of theinvention and the views therein are as follows: ,1 ;Fig. l is a sideview of a lamp guard and -dle arrangement embodying the invention;

"Fig. 2 is a sectional view on the line 2-2 in Fig. 1;

Fig. 3 is a sectional view on the line 3--3 of Fig. 1; and v I Figs. 4and 5 are modified structures embodying the invention.

The lamp guard and handle herein shown for the purpose of illustratingthe invention, comprises a handle I having a longitudinal bore 2 whichreceives a cable 3 containing electrical conductors, the conductorsbeing electrically connected to a lamp socket 4 carried at the upper Thesocket 4 may be of the conventional screw thread formation to receivethreadedly the threaded end 6 of an electric lamp I. The lamp I isprotected by a lamp guard 8 which is connected releasably to theenlarged part 5 of the handle I. p

Thelamp guard 8, as shown, is made of fiber strips 9 extendinglongitudinally of the device, and these strips are connected at theirtops to disks Ill and at their bottoms to a lower collar I I. A centralintermediate or transverse member I2, also made of fiber, is fastened tothe strips 9 to strengthen the guard and add rigidity thereto.Fasteners, such as rivets I3, secure the strips 9 to the parts ormembers I0, II, and I2. The guard 8 may, of course, be made of metal,such as wire, instead of fiber as herein shown.

There have been many ways of securin lamp guards to handles, but allconventional methods require too much time and energy to remove theguard from the handle for the purpose of re- 2 Claims. (Cl. 24054) 2moving or placing a lamp. The average mechanic or other user of a lampand guard handle is adverse to spending time and effort for the simpleprocedure of putting a new lamp in a socket, and therefore, the moresimple and efiicient the attachment is, the more suited it isfor thepurpose. The present invention provides an extremely simple andefiicient device which is capable of 'being readily operated ormanipulated so that the guard may be detached quickly from the handle.The means employed in the present invention for releasably or detachablyconnecting the guard to the handle comprises two or more integral springmembers or clips I4 which are secured to the guard 8 as on the members 9near the collar II. A single clip I4 may be used in conjunction withsome other type of fastener if desired.

In the form of the invention shown in Figures 1 and 2, each spring clipI4 has a straight body portion I5,'the end of which is anchored to amember 9 as by fasteners, such as rivets H. The clip has an inturnedpart I9, spaced fromthe anchored end of the clip to provide a lockingledge or catch to engage a latch keeping shoulder 20 formed on thehandle. An outwardly extending or flaring part 2 I, also integral withthe other parts of the clip, provides a member which can be operatedmanually to release the spring clip or catch from the shoulder 20. Theshape of the part 2| also allows for application of the guard to thehandle by merely pushing the guard downwardly, whereby the clips will bepressed outwardly, thereby expanding it so that it will readily passover the end of the handle, whereupon the shoulder 20 will be home inthe latch part I9 of the clip and the latching part I9 will extend intoan annular groove I9 beneath the collar 20, so that the guard will belocked to the handle. The guard may be released merely by pressing thepart 2| to disengage the locking or latching part I9 from the latchingshoulder, thereby permitting easy and quick detachment of the uard topermit lamp replacement. The guard is re-applied in place merely bypushing the guard downwardly, whereupon the clips will give because oftheir resiliency and then snap back in home position upon the shoulder20. The upper end of the handle is provided with an annular recessedpart forming a seat 22 for receiving the collar I I to facilitate easyapplication of the guard. The seat comprises an annular shoulder uponwhich the collar I I rests. The guard therefor is locked in place uponthe shoulder 22 of the handle by the locking parts I9 of the clips I 4,in co-operation with the latch shoulder 20 beneath which latter the partI9 of the clip engages, the shoulders 20 and 22 facing in oppositedirections on the handle.

In the form of the invention shown in Figure 4, the enlarged part of thehandle is provided with an outwardly extendin peripheral head orprojection and the clip I l has a substantially straight body portion I5secured to the guard member 9, as at H. Adjacent the free end of theclip, there is provided a seat Ill and the extremity of the clip, beyondthe seat, is deflected outwardly, as at Zi to form a means whereby theclip may be deflected, so as to permit the guard to be attached to thehandle, and also engaged by the finger to detach the clip from the heador projection 20*.

In Figure 5, the spring I 5 is provided with the portion [4, which issecured to the guard 9, and is substantially straighbthe free end 19 ofwhich is deflected inwardly to form a shoulder to engage under theshoulder 25', the free extremity 2| of the spring clip being shaped toform a finger-engaging portion, and which also acts as a means todeflect the clip so as to cause it to snap under the shoulder 29, tofacilitate assembly.

The invention provides an extremely simple device for holding, securelybut detachably, a lamp guard to its 'co-operating handle. The device iscapable of very inexpensive manufacture and may be operated with theutmost ease and in a very short time.

Changes may be made in the form, construction and arrangement of theparts without departing from the spirit of the invention, and the rightis hereby reserved to make all such changes as fairly fall within thescope of the appended claims.

The invention is hereby claimed as follows:

1. A lamp guard and handle comprising a handle member having a headformed to receive an electric lamp base, and a guard for a lamp in saidbase comprising a mounting collar and a plurality of spaced guardmembers secured on said collar, said head having an annular seat inposition to receive and support said collar demountably on the seat, andlatching means on said guard for attaching the guard to the headcomprising means forming a latching shoulder on said head and aone-piece spring clip secured to one of said guard members againstlateral movement with respect thereto, said clip having a latchingportion adapted to snap over said latching shoulder and interlockinglyengage the same as said collar is applied to said seat, said clip beingmaintained at all times in a fixed position to permit the clip to snapinto engagement with said latching shoulder when said guard and handleare pressed together.

2. A lamp guard and handle comprising a handle member having a headformed to receive an electric lamp base, and a guard for a lamp in saidbase comprising a mounting collar and a plurality of spaced guardmembers secured on said collar, said head having an annular seat inposition to receive and support said collar demountably on the seat, andlatching means on said guard for attaching the guard to the headcomprising an annular recess on said head and a one-piece spring clipsecured to one of said guard members against lateral movement withrespect thereto, said clip having a latching portion adapted to snapinto said annular recess and interlockingly engage the same as saidcollar is applied to said seat, said clip being maintained at all timesin a fixed position to permit the clip to snap into engagement with saidannular recess when said guard and handle are pressed together.
